Azoo has 15 emperor penguins. who make up 30% of the total numbers of penguins at the zoo. how many penguins live at the zoo?

The best way to find the total is to find what 10% is. A common factor between 15 & 30. Therefore, 5 is 10%. To find 100%, you have to multiply 10 by 10, and therefore, 5 by 10. Therefore, there are 50 penguins at the zoo. Hope this helps :)

The answer is 20^3 because by the end of 6 hours the number of bacteria has doubled every two hours meaning that after the first two hours you have 2000, then another 2000 after two hours, then 4000 after the next two hours, ans finally at the end of 6 hours, you have 8000 bacteria aka 20^3
